Description

The present invention relates to a test driving scenario database system for realistic virtual test driving scenarios. In addition, the present invention relates to a method for examining test drives with such a test drive scenario database system.

Virtual worlds are computer-generated, mostly three-dimensional environments presented and give the user, for example, through interaction with the virtual environment the impression that, for example, change his perspective on objects shown or change his point of view and "move" in it.

Virtual environments are used, for example, in the computer games industry, but also as a tool in product design and development, where the developer can, for example, use a virtual model to customize and test a design for an actual product to be manufactured.

Under certain circumstances, enough information is also available from real scenes or scenarios to generate a virtual scenario based on this, as a model of the real scenario, which realistically maps the real data accordingly.

For example, it is in the US 2010/0030540 provided to reconstruct a traffic accident to generate a three-dimensional accident environment using position data, geographical data and weather data, the vehicle data recorded by a black box of the vehicle, the driver's condition, possibly data from sensors on the road and the geographical To present information in the scene, as well as to represent other objects relevant to the accident, such as nearby vehicles, pedestrians and traffic lights in the scene.

The development and improvement of vehicles and vehicle components can also benefit from their testing in a realistic virtual environment by evaluating real test drives in a virtual environment and, for example, being able to carry out test series adapted to real-world problems with virtual test drives.

In particular, with the development of autonomous and inter-communicating vehicles, the need for reliable tests and simulations has risen to account for all eventualities of complex traffic situations and the behavior of new vehicle components, such as control software for an autonomous, ie driverless vehicle vote. For example, it may be important to understand under which environmental conditions a specific behavior of the control software has occurred and why, for example, a traffic situation has been judged inappropriately or why, despite a correct assessment, a critical situation nevertheless emerged.

In order to be able to sufficiently narrow down the real problems occurring and to be able to identify causes, it is usually necessary to cover even complex relationships, interactions and the influence of different components of the respective test driving scenario, which is only possible to a limited extent with the analysis of individual test drives.

It is an object of the present invention to provide a possibility with which different virtual test driving scenarios that can be generated as realistically as possible from different real test drives can be evaluated.

This object is achieved according to the invention with a test driving scenario database system for realistic virtual test driving scenarios according to claim 1 and a method for investigating test drives with a test driving scenario database system according to claim 14. Advantageous developments of the invention are specified in the subclaims.

According to one aspect of the invention, the test driving scenario database system for realistic virtual test drive scenarios comprises at least one device for displaying a virtual scene, a database memory and a control device. This has at least one data reception unit with one or more data reception interfaces, a configuration unit with at least one user interface and a data output unit with at least one data output interface. The data receiving unit is configured to receive test driving scenario data from a plurality of real test drives of at least one first test vehicle that has at least one first vehicle component to be tested and to store it in the database memory. The configuration unit is configured such that a user of the test drive scenario database system can add at least one annotation to test drive scenario data of at least part of at least one of the plurality of real test drives. And the data output unit is configured to output test driving scenario data from at least the part of the at least one of the plurality of real test runs to which the annotation was added to the virtual scene presenting device, the virtual scene presenting device is arranged to present the output test driving scenario data in a virtual scenario in which one or more parameters of the output test driving scenario data may be changed.

A real test drive, as opposed to a virtual test drive, is performed with a real test vehicle, i. not with the virtual representation of a test vehicle, so that the recorded test driving scenario data relate to values of real parameters of the test vehicle, such as its geographical position, speed, etc., and for example parameters of the driver, the environment of the test vehicle, other vehicles and other road users.

A test vehicle is a driver-controlled or autonomous-driving vehicle having at least one vehicle component to be tested. This implies that a structural addition or modification, but also a change in control or operating software or operation or the entire vehicle is tested, including, for example, a test of the vehicle for certain user groups or in certain test environments. The test vehicle is connected to the database system wireless or wired or connectable. In one embodiment, it is a mobile component of the system or is part of the system.

Among other things, the control device enables wireless or wired communication between the data sources, for example the first test vehicle and environment information databases, the database memory of the test drive scenario database system and the device for displaying a virtual scene. Preferably, for this purpose, all components of the system either wired or wireless, for example, via a 3G, - 4G, 5G or other generation associated mobile network, communicatively connected to each other and are, for example, in the same data cloud or are connected to each other via a data network ,

A test scenario database system comprises the database memory, for example as non-volatile storage or storage facility in a cloud, which can be accessed by the control device, and the device for displaying, ie generating and rendering, a virtual scene, which is for example a programmable device with an output device, eg a screen or a head-mounted display, which receives from the data output unit of the control device the test drive scenario data that has been selected by the user for display. The control device is also a programmable device having a processor and a memory. In one embodiment, it is provided that the control device and the device for representing a virtual scene are realized as a common device.

The selection of the test driving scenario data for transfer to the device for representing a virtual scene is performed by the user, for example a development engineer, via the user interface of the configuration unit, which may be a graphical user interface, for example. At least part of the test driving scenario data of at least one the test drives annotated, ie at least one marker adds and so selects to display. For example, it may be provided to select a time period within the recorded test drive for display.

In one embodiment, it is provided to save selected parts of the test drive scenario data as separate data records during the annotation. In this way, for example, test driving scenario data records can be assigned to specific scenarios, e.g. to be examined, previously insufficiently considered traffic situations or situations in which the test vehicle has behaved differently than expected, have led to a critical situation or have not been sufficiently taken into account during the development process, put together in their own database or database areas for analysis ,

In another embodiment, it is contemplated that the annotation includes adding additional settings for rendering the test driving scenario or other additional information. In one embodiment, it is provided that the user interface of the configuration unit is implemented by the device for displaying a virtual scene, with which a selection or annotation of the test drive scenario data to be displayed is possible directly. In one embodiment, the configuration unit also allows to retrieve further information about the test driving scenarios and add by annotation the test driving scenario data, such as historical data, special events or information about a test campaign to which the test drive belongs. In addition, in one embodiment it is provided to be able to select one as the test vehicle in a test driving scenario with a plurality of vehicles, for example a fleet of interlinked vehicles.

The test driving scenario data is transferred via the data receiving interface or a plurality of data receiving interfaces to the data receiving unit of the control device. Their design is determined by the respective data sources. Sensors preferably already provide sensor signals in digital representation. Analog sensor signals may be converted by the data receiving unit into digital signals. If the data are available via other databases that can be accessed via a wireless or wired connection, an appropriate interface is provided in each case.

Via the data output interface of the data output unit of the control device, the test drive scenario data to be output selected by the user by its annotation for output are transferred to the device for displaying a virtual scene. It can be provided that corresponding virtual representations of objects to which the test driving scenario data to be output are mapped, for example a virtual representation of at least the test vehicle, possibly with the vehicle component to be tested, as well as the other road users, of the device for representing a virtual scene be calculated. In another embodiment, it is provided that already when the control unit stores or stores the received test driving scenario data, it associates corresponding additional information and likewise stores it in the database, so that the test drive scenario data to be output already includes it.

The data receiving unit, the configuration unit and the data output unit of the control device are either implemented as a common module or have interfaces to communicate with each other or at least have an interface for read access to the database memory.

The test driving scenario database system for realistic virtual test driving scenarios provides a possibility of different real test drive characterizing data of both the test vehicle and the vehicle component to be tested together with the environmental conditions collect data characterizing during the test drive together and store it in a database, so that a realistic virtual test drive can be reconstructed on the basis of the stored data.

By providing test driving scenario data records for various test drives in a common database, from which the user can select and process the data to be displayed for the virtual test driving scenario to be displayed, it is possible to specifically examine relationships and dependencies between the parameters of the test driving scenarios and not just individual events, eg Accidents, considered by themselves, but also complex dependencies in extensive scenarios can be detected and analyzed. In addition, for example, more meaningful evaluations of test drives can be obtained by questioning the test drivers during a "repetition" of driving situations in the virtual test drive scenario, which can then be checked with the same test driver in modified scenarios. If it is an autonomous vehicle, the passengers can be interviewed about the test drive.

In one embodiment, the device for presenting a virtual scene not only includes ways to display and interact with a test drive scenario, but also includes or is connected to a driving simulator device that, for example, the virtual representation of the test vehicle in a virtual test drive by a user Driving simulator device can be controlled by the test driving scenario, so that reactions of the test driver to changes in the test driving scenario, including the virtual representation of the test vehicle, can be examined.

The test driving scenario database system described makes it possible to store entire test driving scenarios or selected sections thereof or the data recorded therefrom of the real test environment and of the real test vehicle, including the movements or the data from which the movement can be reconstructed, eg positions above Time, so that the real test drive can be repeated virtually or the real test environment can be modeled virtually. The fact that not only a test drive or a test environment are stored, but many, whole scenarios or parts thereof can be compared and parts are selected so that certain situations, for example, are critical or in which the vehicle or the test Vehicle component has behaved unexpectedly, be taken into account in further developments from the outset or can be considered in other virtual test drives, for example, when performing a virtual clinic ("customer clinic" or "car clinic"), in the test persons, the new vehicle or the test new vehicle component in a virtual 3D world.

In one embodiment of the test driving scenario database system, the received test driving scenario data comprises at least position data of the first test vehicle at a plurality of times or continuously between an associated start and an associated end of a respective test run. The term "between" may also include the times of the beginning and the end of the test drive. The position data are values of a travel parameter and can be determined, for example, using the global positioning system GPS. In this way, the exact route of the test drive can be determined and stored for generating a corresponding virtual test driving scenario. If the time of measurement is additionally recorded in each case, the course of the speed of the first test vehicle is also traceable. For this purpose, the test driving scenario data may include time information, for example a universal time, which is determined by a clock of the test vehicle.

In a further embodiment, the received test driving scenario data comprise values of at least one further driving parameter of the first test vehicle at the plurality of times or continuously between the associated start and the corresponding end of the respective test run. These are, for example, the number and / or the extent of the steering movements, speed and / or acceleration of the vehicle, yaw, inclination, the state of the vehicle headlights, the windscreen wiper, the The selected values of the travel parameter (s) are either transmitted wirelessly to the data input unit of the control device or recorded by the first test vehicle and later transmitted to the data input unit of the test drive scenario database system. The detection of one or more further driving parameters enables an improved realistic reconstruction of the test drive in a virtual test driving scenario. Likewise, RCP (Rapid Control Prototyping) signals or other signals transmitted via the vehicle bus (eg CAN (Controller Area Network)) can be sent to the control device as part of the test drive scenario data or initially stored in a memory of the first test vehicle for later transmission.

In a preferred embodiment, the received test driving scenario data includes environmental data of a surrounding area around the position of the first test vehicle. In one embodiment, the surrounding area is defined, for example, by a certain radius around the position of the test vehicle. Environment data may e.g. Topography data or infrastructure information, such as positions and dimensions of objects, e.g. Positions of traffic lights and other traffic signs, course and width of roads, possibly road slopes, altitude information and / or driving surface information, position, size and orientation of buildings, but also e.g. Weather data for the time of the test drive, status changes of traffic lights, etc. Depending on the intended use of the test driving scenario database, the detection of particular parameter values or their use in the later generation of an associated virtual test driving scenario can be particularly advantageous or even dispensable.

In an exemplary embodiment, the environment data includes data from at least one environment information database. In this case, the environment information database or the environment information databases are either connected to the test driving scenario database system or are part of the test driving scenario database system and are connected to the control device, for example via a wired or wireless connection (s). A connection can, for example, via the Internet be realized. An environment information database may be, for example, a weather data server or map information server. From the weather data server, for example, information on temperature, humidity, rain, snow, visibility and / or historical weather data can be retrieved. Two-dimensional and / or preferably three-dimensional map information of the surroundings of the vehicle position can be called up by the map server. This offers the advantage that the nature of the environment can also be represented in the virtual environment to be generated, and thus, for example, decisions or behavior of the driver that were associated with the nature of the environment (for example lack of visibility of a curve or intersection). The test driving scenario database system makes it possible to investigate the effect of an altered environmental parameter, for example by comparing different test driving scenarios in which certain environmental parameters were different.

In another exemplary embodiment, the environmental data includes further data acquired by one or more sensors of the first test vehicle. In addition to or instead of acquiring environmental data available in corresponding environment databases, in this embodiment it is contemplated to use sensors of the first test vehicle, such as in-board radar, lidar and or camera systems, rain or temperature sensors, in addition to Data of other road users to capture other environmental data such as traffic signs, buildings and / or weather conditions. This offers at least the advantage of being able to record ambient data independently of the existence of a connection to the respective environment information database at any time during the test drive and to be able to record data uniquely associated with the test drive independently of the actuality of the data available in the environment information database. If data is available via an environment information database, position data can be corrected on the basis of the signal returns of the respective vehicle sensors and unidentified echo information can be assigned to associated objects.

In one embodiment, the received test driving scenario data includes position data of one or more other road users, such as other vehicles, pedestrians, or cyclists during the time of the test drive, i. with motion information, in an area around the test vehicle. For example, sensor data from one or more sensors, e.g. Image sensors, which are attached to the first test vehicle. Instead or in addition, for the detection of the position data, direct communication may also be available, if available, for example using a vehicle-to-vehicle (V2V) communication connection or an infrastructure-to-vehicle (I2V), Communication link (for example, traffic light-to-vehicle) or a pedestrian-to-vehicle (P2V) communication link made. Positional data of pedestrians are recorded, for example, via their smartphone. Information about other road users and the traffic situation can also be obtained from traffic information systems and databases, for example the traffic density, position of a traffic jam or accident site or information about the traffic flow, for example traffic light conditions or traffic light phases.

In one embodiment, the first vehicle component to be tested includes control software, and the one or more parameters or at least one of the parameters of the output test scenario data is parameters of the control software. In this way, changes to a control software component can be checked and validated.

In a further embodiment of the test driving scenario database system, the data receiving unit is configured to receive test driving scenario data from real test drives of at least one second test vehicle having at least the first or another vehicle component to be tested and to store it in the database memory. This offers the advantage that, for example, test drives with different test vehicles, but the same or a similar vehicle component to be tested can be detected by the test driving scenario database system.

In an exemplary embodiment, the data receiving unit is configured to receive the test driving scenario data from concurrent real test runs of the first and second test vehicles and to store in the database memory. In this way, even more complex traffic situations can be stored for a realistic virtual test driving scenario, for example in order to be able to analyze the interdependencies of the vehicles with one another or of vehicle fleets, which are e.g. exchange data with each other via a V2V communication connection. To the control unit of the database system, the data either comes from each of the test vehicles separately, or all the data is transmitted to the first test vehicle, which then communicates with the control device of the test drive scenario database system.

In one embodiment, the data receiving unit is configured to receive the test driving scenario data at least in part via a wireless connection. This particularly relates to the data received by test vehicles, but may also relate, for example, to environment information data servers which may be directly accessible, for example via a mobile telephone network or connected thereto via the Internet or other communications network, e.g. are realized as servers in a cloud.

In one embodiment, the virtual scene presentation device includes an analysis unit configured to analyze dependencies between different test drive scenario data. For this purpose, the analysis unit can, for example, generate statistics or tables, such as, for example, one of the parameters changes when another is changed, so that dependencies and relationships can be tracked / tracked and evaluated. For example, the dependence of the fuel consumption of the test vehicle on the number of other road users, the weather or similar. to be examined. For example, there is the possibility to manipulate the virtual scene and to capture the effects and / or data several test drives with different parameter settings. In one embodiment, it is provided that the visualization of the sequence of a selected test drive can be controlled via control commands (eg, play, pause, forward, backward).

In an exemplary embodiment, the analysis unit is configured to automatically annotate changes that exceed assigned tolerance ranges as special events in the test drive scenario data. This can be, for example, sudden steering movements or braking. The use of the test scenario scenario database system allows a detailed analysis of the causes of the events. Performing the event detection for several road users in a test driving scenario or comparing different test drives, can be (so visually) to recognize relationships easier. For example, it would be possible to analyze and recognize that if the speed is above a threshold, a certain surprising obstacle will result in a dangerous steering movement, but not at a reasonable speed below the threshold.

In a further embodiment, the analysis unit is also configured to use a learning algorithm that makes it possible to determine causal relationships between events from the sequence of detected events.

According to a further aspect of the invention, the method according to the invention relates to a method for examining test drives with a test drive scenario database system for realistic virtual test drive scenarios. It is envisaged that the method be carried out with a test driving scenario database system according to one of the embodiments described above. In this way, the advantages and special features of the test driving scenario database system according to the invention are also implemented in the context of a method for examining test drives with a test drive scenario database system.

To this end, the method for examining test drives is implemented with a test scenario database system for realistic virtual test drive scenarios, comprising at least one device for displaying a virtual scene, a database memory and a control device having at least one data reception unit with one or more data reception interfaces, a configuration unit having at least a user interface and a data output unit having at least one data output interface.

The method comprises at least, with the data receiving unit, test driving scenario data from a plurality of real test drives of at least one first test vehicle having at least one first vehicle component to be tested and stored in the database memory, with the configuration unit for test driving scenario data from at least a portion of at least one of the plurality of real test drives, adding at least one user of the test drive scenario database system to the data output unit with test driving scenario data from at least the portion of the at least one of the plurality of real test drives to which the annotation added was to output to the device for displaying a virtual scene and with the device for displaying a virtual scene to display the output test driving scenario data in a virtual scenario in which one or more parameters of the output test driving scenario data ve can be changed.

It should be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. It should be understood that the features of the various exemplary embodiments described above and below may be combined with each other unless specifically stated otherwise. The description is therefore not to be considered in a limiting sense, and the scope of the present invention is defined by the appended claims.

In Fig. 1 an example of a test driving scenario database system for realistic virtual test driving scenarios according to an embodiment of the invention is shown schematically. The shown test driving scenario database system 10 for realistic virtual test driving scenarios comprises a device 11 for displaying a virtual scene. This has at least one programmable device and a display or display, so that based on selected for display test driving scenario data, a virtual test driving scenario generated and displayed on the display means, such as a display, touch screen or head-mounted display. For this purpose, the device for displaying a virtual scene can in particular also include or be contained in a driving simulator.

In addition, the test driving scenario database system 10 shown has a database memory 12 in which test driving scenario data, possibly with associated additional annotations generated or automatically generated by a user, for example a development engineer, can be stored in a test driving scenario database.

In addition, the test scenario scenario database system 10 shown has a central control device 13 that is connected to the device 11 for displaying a virtual scene, the database memory 12, a first test vehicle 16 and all other components of the system is communicatively connected or can be connected for data transmission. The control device has a data reception unit 14 with a data reception interface 15, a configuration unit 18 with a user interface 19 and a data output unit 20 with a data output interface 21.

The data receiving unit 14 receives test driving scenario data from a plurality of real test driving of a first test vehicle 16 Fig. 1 It is shown that the first test vehicle has a first vehicle component 17 to be tested. This may be, for example, control software of the first test vehicle 16 to be tested. The control device 13 stores the test driving scenario data received from the data receiving unit 14 in the database memory 12.

The received test driving scenario data are at least position data of the first test vehicle 16 which is continuously or at certain measuring times, e.g. every 0.1 seconds between start and end of a test drive. For this purpose, the first test vehicle 16 shown has, for example, a GPS receiver.

In the illustrated embodiment of the test driving scenario database system 10, the control device 13 is also connected to a plurality of environment information databases. A first environment information database 22 is a weather information database from which the controller queries weather data associated with the position data transmitted by the first test vehicle 16 during a test drive. A second environment information database 23 is a map information database, preferably with information, to enable a three-dimensional representation of the environment from which the controller 13 can determine map information data about a surrounding area around the respective position of the first test vehicle. In addition, the control device 13 is connected to a third Environment information database 24, from which the traffic information data are retrieved for the environment of the position of the first vehicle.

The first test vehicle 16 also has sensors 25, e.g. Radar, lidar, and / or image sensors that collect information about the environment, especially nearby objects. These are transmitted to the data receiving unit 14 of the control device 13 as further test driving scenario data.

In the embodiment shown, the control device 13 may also detect at least position data of one or more other road users 26, as well as test driving scenario data of at least one second test vehicle 27 with a second vehicle component 28 to be tested.

The configuration unit 18 has a user interface 19 via which the user of the test drive scenario database system 10 can access and add annotations to received test scenario data stored in the database memory 12. An annotation is in particular the marking of the test driving scenario data of one or more real test drives or of a section or part thereof for the selection of data to be displayed by the device for generating a virtual scene 11.

The data output unit 20 is set up to output, via the configuration unit 18, selected test drive scenario data from real test drives, to which an annotation has been added, to the device 11 for displaying a virtual scene.

The virtual scene presentation device 11 generates a virtual test driving scenario based on the received test scenario data, which in turn enables a user of the device to change parameters of the output test driving scenario data. The user of Device 11 may be the same user who has configured the scene to be displayed via configuration unit 18. However, it may also be, for example, a test person, for example as part of a test series for the test vehicle.

In addition, in the illustrated embodiment, the virtual scene presenting device 11 has an analysis unit 29 that can analyze dependencies between different test driving scenario data and that is configured to automatically change, in the test driving scenario data, changes that exceed assigned tolerance ranges annotate special events. These annotations are transmitted to the control device 13, which stores them in the database memory 12.

In the Fig. 1 The division into one block shown for the device 11 for representing a virtual scene and another for the control device 13 is just one possible embodiment. In other embodiments, for example, the control device 13 and the virtual scene display device 11 or the analysis unit 29 and the configuration unit 18 are implemented as a common module.

The recording of test driving scenario data for a reconstruction of a realistic virtual test driving scenario during a real test drive using the test driving scenario database system 10 can proceed as follows, for example:
After the start of the real test drive, the position of the first test vehicle is determined with the aid of GPS and transmitted to the control device 13 for a sequence of measurement times, for example every 0.1 second, and a 3D map of an environment from the second environment information database 23 the position of the first test vehicle 16 retrieved. The map includes, for example, roads, traffic infrastructure, buildings and traffic signs.

For this purpose, the positions of other road users 26 are determined, e.g. via suitable databases such as the third environment information database 24, which provides traffic information, with the on-board sensors 25 of the first test vehicle 16 information or for example via vehicle-to-vehicle communication from other vehicles, such as the second test vehicle 27 or smartphone location of Pedestrians, cyclists or drivers of other vehicles received position information. In this case, it is provided to match the position information obtained via databases or smartphone location with location information on the basis of the object position information determined by the evaluation of the sensor 25 of the first test vehicle 16 and to correct it. If objects are located, but not identified, a corresponding note is added to the test driving scenario data.

In order to enable a more realistic rendering of the scenarios by the device 11 for representing a virtual scene, in one embodiment additionally the orientation of the objects, their next position and their speed are determined and filed. In addition, weather data associated with the weather data is retrieved from the first environment information database 22 to be used in displaying the virtual scene.

If the test vehicle 16 transmits further data, for example, whether the driving light is switched on or the doors are closed, this information is also captured so that it can be taken into account when presenting the virtual test driving scenario. In addition, if available, also traffic signs, in particular the course of the traffic light states are detected.

It should be noted that the detection of the data of the test drive and its transmission to the control device can either be done directly during the test drive, or at a later time when a data connection can be made takes place. For example, the data of the first test vehicle 16 may initially be on board, for example in a data recording device of the test vehicle 16 and the associated environmental data are later retrieved from the environment information databases 22, 23, 24 when the position data of the first test vehicle 16 has been transmitted to the control device 13.

In Fig. 2 FIG. 2 schematically illustrates an example of a method for examining test drives with a test drive scenario database system for realistic virtual test drive scenarios according to a further embodiment of the invention.

In any case, the suitable test scenario scenario database system has at least one device for displaying a virtual scene, a database memory and a control device having at least one data reception unit with one or more data reception interfaces, a configuration unit with at least one user interface and a data output unit with at least one data output interface.

In a first method step 31, it is provided to receive test driving scenario data from a plurality of real test drives of at least one first test vehicle having at least one first vehicle component to be tested with the data receiving unit and to store it in the database memory.
